Streaming to my devil streaming devices via Chromecast only starts after a long wait or does not start at all.

There are many possible reasons why your music stream doesn’t start or only begins after a long delay. The following are the most common causes:

1) Chromecast built-in functionality can vary between providers. It’s therefore important to abide by the instructions given by the provider for using this technology. For instance, some request that users first cast and then start an audio stream while others recommend the reverse order of actions. If you are unsure whether you are casting correctly, please ask your app’s service team for assistance.

2) It can take around 20 seconds or even longer in some cases for a stream to be processed. Contact the provider of the music or audio service you use to learn more.
